A response can fall into one of k = 4 categories with hypothesized cell probabilities given below. If 390 responses are recorded, what are the four expected cell counts for the chi-square test? P1 0.40, P2 = 0.10, P3 = 0.05, P4 E = E2 E4 = II E. In addition to knowing a person's blood type, it is important to also know whether their Rh factor is positive or negative. The blood types of the first 200 individuals to have their blood drawn at a hospital lab on Monday are recorded below. Type Rh Factor AB Positive 61 12 16 77 Negative 9. 9. 8 15 (a) Based on these sample results, does it appear that these two methods of classifying blood types are independent at the a = 0.05 level of significance?
